Essential oils (EOs) are one of the most important groups of plant metabolites responsible for their biological activities. This study was carried out to study the chemical composition and the antimicrobial effects of Artemisia herba-alba and Origanum majorana essential oils against some Gram-positive and Gram-negative bacteria, and a fungal strain isolated from spoiled butter. The plants were collected in the region Azzemour of South West Morocco and the EOs, extracted by hydrodistillation, were analyzed by GC-MS. The antimicrobial activity was determined using the agar paper disc method. The main components of A. herba-alba EO were cis-thujone, trans-thujone and vanillyl alcohol; in O. majorana EO terpinen-4-ol, isopulegol and β-phellandrene predominated. Both essential oils exhibited growth inhibiting activities in a concentration-dependent manner on several microorganism species. Our results demonstrated that O. majorana and A. herba-alba EOs could be effective natural antibacterial agents in foods.
精油（EOs）是植物代谢物中最重要的一类，负责其生物活性。本研究旨在研究Artemisia herba-alba 和 Origanum majorana 精油的化学成分和抗菌作用，对抗一些革兰氏阳性和革兰氏阴性细菌，以及从变质黄油中分离出来的真菌菌株。植物在摩洛哥西南部的 Azzemour 地区采集，通过水蒸馏提取精油，并用 GC-MS 进行分析。采用琼脂纸片法测定抗菌活性。A. herba-alba EO 的主要成分是顺式-侧柏酮、反式-侧柏酮和香草醇；O. majorana EO 中，萜品-4-醇、异松油醇和β-蒎烯占主导地位。两种精油都表现出浓度依赖性的生长抑制活性，对几种微生物有抑制作用。我们的结果表明，O. majorana 和 A. herba-alba EOs 可以成为食品中有效的天然抗菌剂。
